TOYOTA car, (factor cruise or aftermark add on)????????
all cruise controls are very strict, after all they are very dangerous.
modern cars are more strict with PCM and BCM brains.
the service manual covers all this why not read it first and ask questions.
here is list of thing that cause it to fail (besides its switch)
- brake fail , glowing.
- CEL LAMP GLOWING RUNNING. OR AT IDLE.
- TRANSMISSION ERRORS OF ANY KIND (DTC CODES SET)
- TPS ERRORS, THROTTLE POS. SENSOR.
- and the newer the car , more, like ABS errors or traction
what you did not do first is this
check all fuses.
scan the PCM,
is this a USA car not told and they are NOT THE SAME world wide.
you posted to www, forum but no country told
no engine told.
Gen 2 car. the wiki list gen2 cars, world wide shows this.
must we guess them all and answer, 7 times?
------------------------------------------------
the 2004 in usa has
throttle by wire throttle body (motor driven by gears inside)
that means CRUISE is 100% software, (cruse button is the only hardware, just like my jeeps all have.
the cruise software runs that TB motordrive on modern cars.
and to make this simple , scan the PCM and it tells you why
a DTC is set and, cruise is disabled.
CEL lamp glowing and ignored?
some DTCs do not set the CEL lamp and even less in canada
the car must be scanned first..
check fuses
and scan it.
OBD2 scan tools for USA or Canada cars. no country told.
